Some observations on phase noise from local oscillator strings. By KØCQ Dr. Gerald N. Johnson, retired P.E.

all oscillators have amplitude noise which we neglect because BALANCED mixers ignore it. Single diode, FET, and half frequency mixers do not ignore amplitude noise. And any frequency multiplier/ the oscillator voltage regulator isnt modulating the oscillator at any frequency. The common 78L family isnt perfectly quiet. F9HX uses one as a noise source to modulate clean oscillators / FM modulator on my HP8640B has a 250 Khz video bandwidth.
